Hotpoint NDD 9636 DA UK washer dryer venting steam from blower manifold pipe

The problem

The washer dryer was washing and drying adequately, but the kitchen became very humid during drying and very hot air/steam was constantly venting from the short rubber vent pipe on top of the blower manifold.

Likely cause

The accepted reply suggested a condensing problem. The steam from drying should be condensed in the condenser chamber by a small, constantly running trickle of cold water. The discussion suggests this may not be happening, but the exact failed part or blockage was not confirmed.

What fixed it

No confirmed repair was documented. The accepted advice was a diagnosis that the condensing system was likely not condensing the steam correctly. Exact repair steps and the component at fault were not confirmed.
